Who was the U.S. President during both World War II and the Great Depression?

The correct answer is Franklin Roosevelt, who served as the U.S. President from 1933 to 1945. He played a pivotal role during both the Great Depression and World War II. Roosevelt's New Deal programs were designed to address the economic turmoil of the Great Depression, providing relief and recovery to Americans suffering from unemployment and poverty. His leadership and policies helped to stabilize the economy during a difficult period.

During World War II, he was instrumental in mobilizing the nation for war, forming alliances, and leading the United States through some of its most significant military engagements. His ability to inspire and communicate with the public through his fireside chats helped unify the country during these challenging times.

The other individuals listed were not in office during both of these significant periods. Herbert Hoover was President at the onset of the Great Depression but left office before WWII began, while Harry S. Truman assumed the presidency after Roosevelt's death in 1945 and played a role in the latter part of the war and its aftermath. Dwight D. Eisenhower did not become President until after both events had concluded.
